# sdxl-ugly-sonic-lora

![](img/example1.webp)

A LoRA for SDXL 1.0 Base which generates [Ugly Sonic](https://knowyourmeme.com/memes/ugly-sonic), using `sonic the hedgehog` as the trigger keywords.

## Usage

The LoRA can be loaded using `load_lora_weights` like any other LoRA in `diffusers`:

```py
import torch
from diffusers import DiffusionPipeline, AutoencoderKL

vae = AutoencoderKL.from_pretrained(
    "madebyollin/sdxl-vae-fp16-fix",
    torch_dtype=torch.float16
)
base = DiffusionPipeline.from_pretrained(
    "stabilityai/stable-diffusion-xl-base-1.0",
    vae=vae,
    torch_dtype=torch.float16,
    variant="fp16",
    use_safetensors=True
)

base.load_lora_weights("minimaxir/sdxl-ugly-sonic-lora")

_ = base.to("cuda")
```

During image generation, use `sonic the hedgehog` in the prompt.

## Examples

For all generations, the negative prompt used is `blurry, low quality`. Prompt weighting is done using the [compel](https://github.com/damian0815/compel) syntax.

`sonic the hedgehog relaxing on a couch, renaissance painting, (oil on canvas, aged, worn)++++` (cfg = 13)

`a profile of sonic the hedgehog sitting at a desk deep in thought, (pixel art)++++, award-winning photo for vanity fair` (cfg = 13)

`anatomical diagram of sonic the hedgehog, (highly detailed)++++` (cfg = 13)

`sonic the hedgehog (eating at McDonald's)++, Ukiyo-e, minimalistic vector art` (cfg = 13)

![](img/example5.webp)

`(hyperrealistic++ death metal album cover)+++ featuring edgy moody realistic human sonic the hedgehog, edgy and moody` (cfg = 13)

`(hyperrealistic tall human)+++ sonic the hedgehog cameoing in an (episode of Friends)+++++, high quality hyperrealistic promotional photo` (cfg = 13)

## Methodology

This LoRA was trained on frame-by-frame analysis of the [original 1080p trailer](https://www.youtube.com/watch?v=4mW9FE5ILJs) featuring "Ugly Sonic". Square-crops of Ugly Sonic were extracted and AI-upscaled to 1024x1024 for optimial training.

The use of `sonic the hedgehog` as the trigger keywords (and training the LoRA on said keywords) ensures that you won't generate the _other_ hedgehog by accident. Because no one likes him.

## Notes

- The CGI style of Ugly Sonic may overpower other style prompts. Therefore, you should weight any style prompts much higher, as done in the examples.
- Attempting to generate any humans with this prompt may generate half-hedgehog half-human hybrids. This may be a pro or con depending on what you are going for, but you can specify `human` and weight accordingly.
